Hello,
I have a subroutine in which I make several calls to different subroutines. Each call has this syntax:
$error_msg = sub1();
return $error_msg if ($error_msg ne ());

$error_msg = sub2();
return $error_msg if ($error_msg ne ());

[download]
and so on several times.

In these routines (sub1, sub2..) I have returns with messages if anything goes wrong. Otherwise I end with return ();
Is there a way I can avoid to check after each call the content of $error_msg, in order to return to the caller, and have it "implicitly" present in the subroutine ?

Thank you,
Roberto
